(534) بَابُ اسْتِقْبَالِ الْقِبْلَةِ
Munqidh said, "In most of the gatherings of 'Abdullah ibn 'Umar,he would face qibla. Once Yazid ibn 'Abdullah ibn Fusayt recited Sajdaafter sunrise. He prostrated and the people there prostrated with the exceptionof 'Abdullah ibn 'Umar. When the sun rose, 'Abdullah uncurled his legsand then prostrated. He said, 'Did you see the prostration of your companions?They prostrated at a time when the prayer should not be done."
